Abstract
Description
- 1. Field of the Invention
- The subject matter described herein relates generally to power busways and, more particularly, to securing a busway housing to busway power conductors.
- 2. Related Art
- Power busways used within multi-phase electric power distribution systems generally consist of long, rectangular bars of copper or aluminum material. Each individual bar is electrically insulated to maintain electrical isolation between the individual phases as well as between the phase conductors and the neutral conductors. In accordance with electrical codes, a ground conductor must be associated within the busway power distribution system.
- U.S. Pat. No. 4,804,804 entitled “Thermally Efficient Power Busway Housing” describes a two-piece extruded aluminum alloy housing shaped to provide support and ground conduction facility to power busway conductors described above. The two-piece housing is attached together with snap-fit connectors along its top and bottom surfaces. The housing is attached to the busway power conductors by means of insulated bolts.
- General Electric's Spectra™ Series Busway uses a unique double-insulated tie bolt to attach the aluminum housing to the busway power conductors. The tie bolts are inserted through the center of the busway providing predictable consistent strength and high short circuit rating.
- While it is effective to use insulated bolts to secure a busway assembly, a large number of bolts are necessary. Furthermore, using bolts complicates the art of busway construction as the bolts themselves may not come in contact with any part of the bus conductors since the busway housing is generally at ground potential. Therefore, it is desirable to provide an improved means for securing a busway assembly that eliminates the use of bolts, uses fewer components, but still provides predictable consistent strength and high short circuit rating.
- In accordance with an embodiment of the present invention, a power busway assembly comprises a pair of opposing non-ferrous metal apertured side plates. The side plates have a U-shaped configuration and intern comprise a pair of top and bottom flanges that are joined by a flat piece. The power busway assembly further comprises a means on one end of each of the flanges for interlocking the side plates together. The interlocking means intern comprises an angulated projection or an angulated slot. First rails extending from one of the pairs of flanges are also included that provide hanger support connection means. In addition, second rails extending from another one of the pairs of flanges are included that provide ground stab connection means. The power busway assembly further comprises at least one brace that is interconnected with the flanges. The brace is dimensioned and configured to bias the interlocking means together.
- In another embodiment of the invention, a method of securing a busway housing to busway power conductors comprises using a plurality of braces. The busway housing comprises a pair of opposing non-ferrous metal apertured side plates. The side plates have a U-shaped configuration and intern comprise a pair of top and bottom flanges that are joined by a flat piece. The top and bottom flanges comprise slits, and the plurality of braces comprises a hooked end and a flanged end. The method comprises inserting the hooked end into one of the slits, and rotating the brace until the flanged end is adjacent to another of the slits. The method further comprises providing an axial force to the flanged end, wherein the force is perpendicular to the side plates, and whereby the flanged end completely engages the another of the slits.
